alt是否与alt =“"相同? [英] Is alt the same as alt=""?

问题描述

我正在为所有图像添加alt属性，以提高SEO/屏幕阅读器的性能.

I'm adding alt attributes to all my images to improve SEO/screen reader performance.

按照最佳实践，纯美感的图像应具有一个空的alt属性alt=""，因此屏幕阅读器会跳过它们.我在WordPress中，发现它确实将alt添加到了这些无描述的美学图像中，但没有添加alt="".

Per best practice, images that are purely aesthetic should have an empty alt attribute alt=""so screen readers skip over them. I'm in WordPress and noticed it does add alt to these descriptionless aesthetic images, but not alt="".

屏幕阅读器和搜索引擎搜寻器是否读取alt与alt=""相同，还是我应该以编程方式强制使用alt=""?

Does alt get read the same as alt="" by screen readers and search engine crawlers, or should I go in and programatically force an alt=""?

推荐答案

是的，是一样的: https://www.w3.org/TR/html5/syntax.html#attributes-0

空属性语法

Empty attribute syntax

只是属性名称.该值隐式为空字符串.

Just the attribute name. The value is implicitly the empty string.

对我来说，这意味着没有值的属性与具有空字符串的值相同.

To me, that says that an attribute with no value is the same as having a value of empty string.
